All user posts don't work properly

My app’s URL:

Take Jack’s Instagram tutorial from '30 to '33 and try to reproduce the display of posts per user within the new logic.

Shortly speaking, instead of showing each user’s posts, it shows only the posts of the first user in the Profile table in the spreadsheet.

P.S. at the moment doing a workaround so you might not find all replicated steps in my app, but you are free to replicate them there.

Closing this to keep the discussion to the post below.
